why arent there any triangle planets??

Answer 1

There probably used to be. But you start getting your planet big enough, and gravitational force will start taking those triangular corners and sucking them into the center of the planet until you have a sphere-like object.

Answer 2

There are no triangle planets because the force of gravity smooths out any edges and has every point of the entire planet trying to get to the exact center at the same time. Coupled with the centrifugal force of the planet spinning, there is no such thing as a planet in any other shape than a rough sphere or oval planetiod shape.

Answer 3

For the same reason there are no triangular raindrops. At a size of thousands of miles, rock is as weak as water and gravity tries to pull everything into the center. Since each part of the planet gets in the way of each other part as they all try to get to the center, they end up in the shape that gets the maximum amount of mass into the smallest volume, which is a sphere.

Answer 4

There are several reasons. The Earth in it's early history was molten to the surface, the sparse crust was thin and spotty.

So, because the earth is rotating, it is the subject of some centrifugal force and, as mentioned earlier, gravity. These forces work pretty much equaly in all directions. And so, like when you fill a ballon with air, it presses equaly and becomes the most natural shape it can, which is round. Gravity pulls in and centrifugal force presses out.

This pressure sandwich, does a pretty good job of leveling out dents or obtrusions, leaving us with a roughly spherical shape.

Answer 5

for the same reason there are no square or octogonal shapes etc. Gravity, which pulls the planets in their orbits creates the most efficient shape, which is spherical. If you release a drop of water, the gravity will make the water turn to a small circle...the same mechanics work on planets. In fact, with our knowledge of this fact, we used to create cannon balls by dropping liquid metal from a tower...it would form the shape of a ball and then hit water to solidify it into a cannon ball.

Answer 6

Well since we only know about the planets in this solar system we cannot rule out that there might be some odd shaped planets in the universe, but they're probably all somewhat eliptical because of how they are formed.

Answer 7

Its a rule. When Pluto was kicked of the list of major planets the astronomers said that a Planet must be big enough for its gravity to pull itself into a round ball. pyramid shaped pieces or rock wouldn't qualify as planets. We also know that if they got big enough their own gravity would round out the points into a ball.

Answer 8

There's nothing wrong with them, but their gravity will eventually shrink them into "better" shapes (spheres). I suppose it's possible, and the asteroids are small enough that they don't have strong enough gravity to be spheres. They are all kind of shapes.

Answer 9

there are no triangular planets, but there are people who are squares.....lol

Answer 10

who knows, who cares
